Kevlar纤维及碳纤维背衬下SiC陶瓷和弹丸的破碎特性
Crushing Characteristics of SiC Ceramics and Projectiles under Kevlar/Carbon Fiber Backing
摘要
Abstract
There is a clear correlation between the ballistic performance of ceramic/fiber composite armor and the fragmentation characteristics of the projectile and target.When the back-plate material is different,the difference in wave impedance will cause differences in stress wave transmission between the ceramic and back-plate interface,resulting in different fragmentation outcomes of the projectile and ceramic panel,leading to differences in the protective performance of the composite target.For the differences in the fragmentation characteristics of the projectile and target,when the projectile penetrates different fiber back-plate ceramic composite armors,ballistic tests of 12.7 mm armor-piercing incendiary projectile penetration of ceramic/Kevlar fiber composite targets and ceramic/carbon fiber composite targets were carried out,and the protective performance of the two types of ceramic/fiber composite targets was analyzed in conjunction with the test results and the Rosin-Rammer distribution model.The results show that the fracture of the bullet core is mainly caused by the internal shear stress.When the back-plate material is carbon fiber,the average characteristic size of the bullet core fragments is reduced by 21.68%compared with Kevlar fiber,and the average characteristic size of the ceramic fragments is reduced by about 9.48%,that is,the proportion of small-sized fragments of the bullet core and ceramics is larger,and at the same time,the overall ballistic performance of the composite target is better.关键词
